' a My invention has relation to producing from cast iron a metalproduct adapted to take a temper.

My invention, basically considered, consists of a metal product havinthe chemical constituency of cast iron and the physical pro erty oftaking a tem or.

The nature and enera scope of my invention will be more ully understoodfrom the following description taken in connection with the accompanyingdrawing forming part hereof, in Which Figure 1, is a view of a plantsusceptible, instrumentally, of being employed to produce the metalproduct embodying the features of my said invention ,and Fi 2, is a viewin perspective, illustrativ'ely, 0 the metal product adapted to take atemper, derived from cast iron according to my invention.

Referring to the drawing 1, represents a cupola -furnace provided with apouring spout'a, and ladle a, the ladle being placed in roximity to apermanent sectional metal mo (1 2, consisting of a cope b, and drag 1;,having pour-holes b, located about the meeting edge of the two sectionsof the mold 2, and having internal channelways, not shown, directlyleading to a central cavity 1), of any required shape or form, accordinto the shape or form of the homogeneous so id struc ture to be cast inthe mold. The molten metal from the cupola-furnace 1, asses by thepouring-spout a, into the lad e a, and then into the mold 2, in whichitswiftly chills Specification 01 Letters patent.

that the cast structure, set in the mold can immediately be removed. Itcan then be quenched in a tank of water 3, while still hot and give aresultant product having the chemical constituency of cast iron and someI It has a r of the physical properties of steel. also beendemonstratedthat the metal prod.-

not, as hereinbefore described, may be sub- 1ected to magneticinfluences and retain sufficient magnetism to become, due to thecharacter of the metal, a permanent magnet. Having thus described thenature and objects of my invention, what I claim as new and desire tosecure by Letters Patent is:

1. As a new article of manufacture, ametal product having theconstituency of cast iron and property of taking a temper.

2. As a new article of manufacture, a homogeneous metal product havingthe constituency of cast iron and property of taking a temper.

3. As a new article of-manufacture, a homogeneous metal product havingthe chemical constituency of cast iron and physical property oftakiug atemper.

4. As a new article of manufacture, a metal product having theconstituency of cast iron and property of becoming, by the characterthereof, a permanent magnet.
